The response of the Great Barrier Reef to major environmental changes
LESSONS FROM THE GEOLOGIC PAST
Declines in coral coverage across much of the Great Barrier Reef in the past 30 years, along with massive bleaching in 2016/17, has brought issues around coral reef resilience into sharp focus. Predicting how the GBR will respond in the face of future global climate changes is crucial if we are to effectively manage this valuable system. Our ability to predict future changes depends on our knowledge of the responses of reef ecosystems to previous environmental changes over different spatial and temporal scales. Those responses are commonly preserved beneath the living reef surface.
Working with a team of national and international scientists, Jody and his team have collected fossil coral reef cores from the edge of the continental shelf of the GBR, in water depths up to 130 m. Analysis of these ancient coral reefs reveals exciting information about past sea level and climate changes, which aids prediction of future reef behaviour.
About our speaker:
Associate Professor Jody Webster is the co-coordinator of the Geocoastal Research Group (GRG), in the School of Geosciences at the University of Sydney.
Jody's research is focused on coral reefs, both modern and ancient, as tools to address questions about sea level and paleoclimate change and in turn, the influence of these factors on reef evolution. His research tends to take him to all the beautiful places in the world (e.g. the Great Barrier Reef, Tahiti, Hawaii, Papua New Guinea, Seychelles, Brazil).
